Re: Deadly Amoebas Found in Tankless Water Heater

said by Jack_in_VA:

There is no rational reason to exceed the CDC recommendation of 120 degrees for the the setting.

Or maybe there is:
said by CDC :
Households with water heater temperatures <=125°F were significantly more likely to harbor nontuberculous mycobacteria (NTM) compared with households with hot water temperatures >=130°F...

Nontuberculous mycobacteria (NTM) are opportunistic pathogens found in the environment (e.g., water and soil) and cause life-threatening infections in humans, other mammals, and birds. The incidence of NTM disease in Canada and the United States seems to be increasing... NTM are not transient contaminants of drinking water distribution systems; rather, the NTM grow and persist in plumbing.

NTM disease cases number less than 4,000 per year, and the -vast- majority of those cases are from environmental airborne exposure.
Since, you know, you have to inhale them to contact disease from them. A hotter shower is actually much more dangerous of a risk exposure because of that.
